Yo Unregistered: Join us for the April 1 meeting when it will be Recovery night. We will have demonstrations working with winching, recovery and spotting. We will meet at 7:30 p.m. at Jefferson County Fairgrounds (not Stevinson Toyota but nearby).

ok - so this may be a "duh" to most, but just a reminder for older obd vehicles. O2's don't always through a code. I bought this t100 used of course, and one of the reasons was that the PO did just about every PM thing known to man. Since buying the truck though, my mpg just kept going down where it finally stopped at 13.5 or so combined city/highway....

I pulled codes, and nothing there.. So, I went through the documentation of what he had replaced, and low and behold, no O2 replacement. I promptly replaced them and cleaned the MAF.

They were caked, and rightly so, at 168k miles. Average life on an O2 is around 120k, so there you go.

mpg is now back up to a respectable 18.2 combined..

I was running in limp mode it turns out, at full rich.

o2's on the 3.4 are pre and post cat. Held in by flange bolts, and take like 10 minutes. NEVER buy generic. Either buy direct fit replacement by bosch or the oem toyota. Bosch makes most of the oem anyway.
